Summary
The Horizontal Vertical Flame Tester provides rapid, reproducible combustion evaluations for solid polymers, insulating plastics, and electrical component housings. Built around UL 94, IEC 60950-1, and IEC 60695-2-2 benchmark standards, the equipment features a 0.75 m³ anti-corrosive stainless steel enclosure, multi-angle burner adjustment (0°, 20°, 45°), and PLC-driven digital timing. It accurately determines burning rate, afterflame duration, and afterglow persistence to help laboratories achieve material safety compliance.
Understanding Material Flammability Testing
Controlling fire risk in electrical hardware and consumer goods starts with rigorous material-level testing. The Horizontal Vertical Flame Tester creates a controlled environment to simulate real-world ignition scenarios on standardized specimen bars.
Engineered with a robust stainless steel housing and an oversized clear window, the chamber allows technicians to continuously monitor test behavior without exposure to open flames or smoke. High-accuracy digital sensors track ignition cycles and burn durations down to tenths of a second, providing the precise data points required for global safety certification.
